Non-Reciprocal Spin Pumping in Asymmetric Magnetic Trilayers
Yevgen Pogoryelov, Manuel Pereiro, Somnath Jana +9
In magnetic trilayer systems, spin pumping is generally addressed as a reciprocal mechanism characterized by one unique spin mixing conductance common to both interfaces. However,…
Domain wall-based spin-Hall nano-oscillators
N. Sato, K. Schultheiss, L. Körber +7
In the last decade, two revolutionary concepts in nano magnetism emerged from research for storage technologies and advanced information processing. The first suggests the use of m…
Employing machine learning for theory validation and identification of experimental conditions in laser-plasma physics
A. Gonoskov, E. Wallin, A. Polovinkin +1
The validation of a theory is commonly based on appealing to clearly distinguishable and describable features in properly reduced experimental data, while the use of ab-initio simu…
Kulikov singularities
Jan Stevens
In the study of normal surface singularities the relation between analytical and topological properties and invariants of the singularity is a very rich problem. This relation is p…
Digital video microscopy enhanced by deep learning
Saga Helgadottir, Aykut Argun, Giovanni Volpe
Single particle tracking is essential in many branches of science and technology, from the measurement of biomolecular forces to the study of colloidal crystals. Standard current m…
A Casimir preserving scheme for long-time simulation of spherical ideal hydrodynamics
Klas Modin, Milo Viviani
The incompressible 2D Euler equations on a sphere constitute a fundamental model in hydrodynamics. The long-time behaviour of solutions is largely unknown; statistical mechanics pr…
A quotient of the Lubin-Tate tower II
Christian Johansson, Judith Ludwig, David Hansen
In this article we construct the quotient M_1/P(K) of the infinite-level Lubin-Tate space M_1 by the parabolic subgroup P(K) of GL(n,K) of block form (n-1,1) as a perfectoid space,…
The interchange process with reversals on the complete graph
Jakob E. Björnberg, Michał Kotowski, Benjamin Lees +1
We consider an extension of the interchange process on the complete graph, in which a fraction of the transpositions are replaced by `reversals'. The model is motivated by statisti…
Helicoidal particles in turbulent flows with multi-scale helical injection
Luca Biferale, Kristian Gustavsson, Riccardo Scatamacchia
We present numerical and theoretical results concerning the properties of turbulent flows with strong multi-scale helical injection. We perform direct numerical simulations of the…
Laser-particle collider for multi-GeV photon production
J. Magnusson, A. Gonoskov, M. Marklund +7
As an alternative to Compton backscattering and bremsstrahlung, the process of colliding high-energy electron beams with strong laser fields can more efficiently provide both clean…
Constructing KMS states from infinite-dimensional spectral triples
Magnus Goffeng, Adam Rennie, Alexandr Usachev
We construct KMS-states from -summable semifinite spectral triples and show that in several important examples the construction coincides with well-known direct cons…
Quantum spins and random loops on the complete graph
Jakob E. Björnberg, Jürg Fröhlich, Daniel Ueltschi
We present a systematic analysis of quantum Heisenberg-, XY- and interchange models on the complete graph. These models exhibit phase transitions accompanied by spontaneous symmetr…
Quantum error correction for the toric code using deep reinforcement learning
Philip Andreasson, Joel Johansson, Simon Liljestrand +1
We implement a quantum error correction algorithm for bit-flip errors on the topological toric code using deep reinforcement learning. An action-value Q-function encodes the discou…
Survey of Computational Approaches to Lexical Semantic Change
Nina Tahmasebi, Lars Borin, Adam Jatowt
Our languages are in constant flux driven by external factors such as cultural, societal and technological changes, as well as by only partially understood internal motivations. Wo…
Bayesian Data Analysis in Empirical Software Engineering Research
Carlo A. Furia, Robert Feldt, Richard Torkar
Statistics comes in two main flavors: frequentist and Bayesian. For historical and technical reasons, frequentist statistics have traditionally dominated empirical data analysis, a…
Quench dynamics and zero-energy modes: the case of the Creutz model
R. Jafari, Henrik Johannesson, A. Langari +1
In most lattice models, the closing of a band gap typically occurs at high-symmetry points in the Brillouin zone. Differently, in the Creutz model describing a system of spinle…
Magnetic field sensing with the kinetic inductance of a high- superconductor
V. Vesterinen, S. Ruffieux, A. Kalabukhov +5
We carry out an experimental feasibility study of a magnetic field sensor based on the kinetic inductance of the high- superconductor yttrium barium copper oxide. We…
Structure and evolution of magnetohydrodynamic solitary waves with Hall and finite Larmor radius effects
E. Bello-Benítez, G. Sánchez-Arriaga, T. Passot +2
Nonlinear and low-frequency solitary waves are investigated in the framework of the one-dimensional Hall-magnetohydrodynamic model with finite Larmor effects and a double adiabatic…
Exchange dependent ultrafast magnetization dynamics in FeNi alloys
Somnath Jana, Ronny Knut, Erna K. Delczeg-Czirjak +13
Element specific ultrafast demagnetization was studied in FeNi alloys, covering the concentration range between . For all compositions, we observe a delay…
Inhomogeneous magnon scattering during ultrafast demagnetization
R. Knut, E. K. Delczeg-Czirjak, S. Jana +20
NiFe (Py) and Py alloyed with Cu exhibit intriguing ultrafast demagnetization behavior, where the Ni magnetic moment shows a delayed response relative to the Fe, an…
Misaligned Values in Software Engineering Organizations
Per Lenberg, Robert Feldt, Lars Göran Wallgren Tengberg
The values of software organizations are crucial for achieving high performance; in particular, agile development approaches emphasize their importance. Researchers have thus far o…
Numerical upscaling of discrete network models
Gustav Kettil, Axel Målqvist, Andreas Mark +3
In this paper a numerical multiscale method for discrete networks is presented. The method gives an accurate coarse scale representation of the full network by solving sub-network…
Semi-invariant Riemannian metrics in hydrodynamics
Martin Bauer, Klas Modin
Many models in mathematical physics are given as non-linear partial differential equation of hydrodynamic type; the incompressible Euler, KdV, and Camassa--Holm equations are well-…
Hyper-Algebras of Vector-Valued Modular Forms
Martin Raum
We define graded hyper-algebras of vector-valued Siegel modular forms, which allow us to study tensor products of the latter. We also define vector-valued Hecke operators for Siege…
